It depends on which "Connection Reset" problem you are referring to.
Reported by the browser, or seen as as a Squid error message?
Squid has historically been as sensitive as most browsers is on Unix.
I.e.
if it sees a "Connection Reset" message when trying to contact the
origin
server then request failed. Windows browsers on the other hand retries
requests when seeing a "Connection Reset". I think this is addressed by
the current code.

The retry patch is partially incorporated in Squid 2. Work is being
made on a more complete retry model including false hit recovery.

Not all are cache specific, but people notice them when using a Squid
as Squid may do things differently than the origin server, or the
browser behaves slightly different when using a proxy..
Netscape:
Persistent proxy connections and https requests.
FTP URL style.
Spaces in URLs.
Range requests in some versions / plugins.
IE:
Persistent proxy connections when not allowed by the proxy...
Possibly other connection / HTTP issues.

This is not unique to the emx library. The same applies to CygWin on
Windows. Search for _SQUID_MSWIN_ in store_dir.c (no idea why Duane

I got that one. I changed the code to as follows
#if defined(_SQUID_MSWIN_) || defined(_SQUID_OS2_)
/*
* You can't rename open files on Microsoft "operating systems"
* so we close before renaming.
*/
storeDirCloseSwapLogs();
#endif
/* rename */
for (dirn = 0; dirn < N; dirn++) {
if (fd[dirn] < 0)
continue;
#ifdef _SQUID_OS2_
file_close(fd[dirn]);
fd[dirn] = -1;
if (unlink(cur[dirn]) < 0) {
debug(50, 0) ("storeDirWriteCleanLogs: unlinkd failed: %s,
%s\n",
xstrerror(), cur[dirn]);
}
#endif
if (rename(new[dirn], cur[dirn]) < 0) {
debug(50, 0) ("storeDirWriteCleanLogs: rename failed: %s,
%s -> %s\n",
xstrerror(), new[dirn], cur[dirn]);
}
}
#if !defined(_SQUID_MSWIN_) && !defined(_SQUID_OS2_)
storeDirCloseSwapLogs();
#endif
The current problem shows up in storeDirCloseTmpSwapLog(). The
file_close() doesn't always really close the file, and hence the unlink
fails (I have to unlink before the rename).

If flags.write_daemon is set then there is more data to write
to the file. You probably don't want to close it before
all has been written.
If you must, I guess you could do something ugly like
call fd_table[fd].write_handler(fd, fd_table[fd].write_data);
I'm not sure what will happen next though.

hello
I recently upgraded from 1.1.21 to 2.0.PATCH2 to 2.1.PATCH1 on linux
2.0.36 with libc5
The problem I'm facing is that I'm getting a lot of BAD REQUEST errors
that weren't there before.
I'm running transproxy 0.4 in conjunction with the transproxy feature in
the kernel to redirect to squid.
I didn't change anything in the configuration except the translation to
the new format.
Any ideas/thoughts?
Thanks in advance

Hi there,
I'm trying to set up Squid as an accelerating proxy for a web server
behind a firewall using virtual hosts, but I keep getting "WARNING:
Forwarding loop... for 'www.company.com.au' -> proxy.company.com.au
I have read the FAQ and the mailing list archives and did everything I
thought I was supposed to.... (but obviously missed something)
http_port 80
httpd_accel_port 80
httpd_accel_host realserver.company.com.au
httpd_accel_uses_host_header on
'realserver.company.com.au' has a valid entry in /etc/hosts and can be
pinged etc. The virtual URL's (www.company1.com.au, www.company2.com.au
etc) have been CNAME'd as the computer with squid running (which is also
aliased as mail, proxy etc.). The interesting thing is that when I turn
_uses_host_header off it gets through fine, with no forwarding loops, I
just get the same homepage regardless of which of the virtual URL's I
use (as you would expect)...
I'm running Squid/2.0.PATCH2 on Debian Linux 2.0.34, anybody know what's
going wrong??
Thanks
Toby

The problem you are having here is that in your setup squid will use a
host_header name over the httpd_accel_host if a host header is
specified (this is what httpd_accel_uses_host_header means, hence the
warning in the sample config).
Therefore, a request to http://www1.company.com.au/ with a host header of
www1.company.com.au (as most browsers do) will cause squid to fetch
http://www1.company.com.au/ instead of http://realserver.company.com.au/
which is itself (thus causing the loop). You should only need to use
httpd_accel_uses_host_header when doing transparent proxying, or when
accelerating multiple virtual servers that use different IP addresses
(this usually employs an internal/external DNS setup).
All you should need to do is disable httpd_accel_uses_host_header. Squid
should forward the specified Host: header with the accelerated request to
realserver.company.com.au.
Note that if realserver.company.com.au doesn't resolve to the IP address
of your named virtual host address, then you will always be returned the
same page.
Try telnetting to realserver.company.com.au:80 and typing this:
GET / HTTP/1.1
Host: www1.company.com.au
Do you get what you expected?

I'll be applying it to my main proxy tomorrow, however I won't see
anything until other ISPs which peer with us turn cache-digests back on.

It seems to cover the case of fulfilling a request which would otherwise
be denied if we've got a false hit in the (current) cache-digest.
It also covers the case of if a peer retrieves a cache-digest, we discard
an object, the peer then requests the object.
That still leaves a window of up to an hour between when we discard an
object/generate cache-digest without said object, and a when peer
retrieves the latest cache-digest without the object in it, possibly
longer if the peer is disconnected, during which time the peer's client
will get our 'Bugger off, not letting you have this object'.
Hmmm... its starting to get too much effort to keep the previous (X) cache
digests around to deal with that aspect.
Skimming store_digest.c, around line 190 says "this object won't be added
to the digest as we're going to toss it out before the next rebuild", so
that seems to cover most cases, although I'd be inclined to trust in the
Note there and increase that amount of time, ie:

RFC952:
1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
sign (-), and period (.). Note that periods are only allowed when
they serve to delimit components of "domain style names". (See
RFC-921, "Domain Name System Implementation Schedule", for
background). No blank or space characters are permitted as part of a
name. No distinction is made between upper and lower case. The first
character must be an alpha character. The last character must not be
a minus sign or period. A host which serves as a GATEWAY should have
"-GATEWAY" or "-GW" as part of its name. Hosts which do not serve as
Internet gateways should not use "-GATEWAY" and "-GW" as part of
their names. A host which is a TAC should have "-TAC" as the last
part of its host name, if it is a DoD host. Single character names
or nicknames are not allowed.
>Any help welcome.
Sorry, but you will have to change the hostname if you think standards are
useful. Squid can be configured to cheat but also DNS-servers might reject
this. Bind8.x rejects this (normally) if you have this in your configuration.
Bind will not accept this zone. Also a secondary bind8.x will not accept this
behaviour from the "master" so in fact you are not doing yourself a vafour if
you don't change the name.
(I admit this is not easy to find in the stack of RFC's but now you know...)

Yes. Both cases are false hits, just two different reasons for "false":
digest collisions and refresh algorithm.

(a) The window between digest rebuilt and other caches asking for a new
digest should be small in most cases (several minutes, not an hour)
(b) New digest in most cases is more than 90% the same as the old one so the
rebuild itself will not cause a lot of false hits.

If a peer is disconnected, Squid will detect that and will not use the digest
from that peer until the peer is back. Meantime, Squid will try to re-fresh
the peer digest and is likely to fail (since the peer is disconnected) and
disable the digest.

I do not think there is any good reason to start keeping old digests (except
during the rebuild process).

You sure can do that. Just note that it will cause more false hits (handled
correctly or not). Also, you probably do not have to patch Squid to achieve
similar effect. Try using the default "." refresh pattern for that (not
exactly the same, but probably close). Refresh statistics in cache manager
will show you how many objects (%) you have digested.

Hello,
thanks for all the replies on my previous questions. Both
problems are solved now.
And, yes, I know about the RFC952 and the illegal undescore.
But the machine is only inside our firewall and no DNS servers
will ever know it's there.
But now I ran into another problem. I still have two proxies
in a hierarchy.

sometimes not all images on the opened page are loaded.

Note, that the html file itself is loaded, only some of the
embedded pictures are not.
Since this is not happening always, but only in about 60% of all
requests, I'm not sure what it is about.
I tried to fiddle around with several timeout settings, but it
didn't changed this behaviour.
Again, any help welcome.

To throw another point of view: We keep the logs on the same set of discs as the cache. Rationale: a) system disc is too small to keep logs on (old Suns with 0.5Gb discs) b) with ICP logging off the load on a disc with logging << cache discs, c) so better to smear everything out on striped set of discs (I know there is a reliability trade off here ...) using Online DiscSuite. Comes down to what discs you have and what is the best use of their bandwidth. -- ----------------------------------------------------------------------------- | Peter Polkinghorne, Computer Centre, Brunel University, Uxbridge, UB8 3PH,| | Peter.Polkinghorne@brunel.ac.uk +44 1895 274000 x2561 UK | ----------------------------------------------------------------------------- -------------------------------- End of squid-users-digest Digest V98 Issue #314 ***********************************************Received on Wed Nov 25 1998 - 09:19:25 MST
